“…These materials are typically mesoporous and macroporous, with limited micropore volume, and they facilitate the adsorption of heavy metals from the liquid phase. Because porous carbon materials are carbonaceous substances with a good degree of porosity and a large particle surface area, they have been a popular adsorbent for many years [ 93 , 94 , 95 ]. Through carbothermal reduction, Zhuang et al (2014) developed a new porous carbon (PC)-encapsulated iron composite.…”

Water contamination is one of the most urgent concerns confronting the world today. Heavy metal poisoning of aquatic systems has piqued the interest of various researchers due to the high toxicity and carcinogenic consequences it has on living organisms. Due to their exceptional attributes such as strong reactivity, huge surface area, and outstanding mechanical properties, nanomaterials are being produced and employed in water treatment. In this review, recent advances in the use of nanomaterials in nanoadsorptive membrane systems for wastewater treatment and heavy metal removal are extensively discussed. These materials include carbon-based nanostructures, metal nanoparticles, metal oxide nanoparticles, nanocomposites, and layered double hydroxide-based compounds. Furthermore, the relevant properties of the nanostructures and the implications on their performance for water treatment and contamination removal are highlighted. The hydrophilicity, pore size, skin thickness, porosity, and surface roughness of these nanostructures can help the water permeability of the nanoadsorptive membrane. Other properties such as surface charge modification and mechanical strength can improve the metal adsorption effectiveness of nanoadsorptive membranes during wastewater treatment. Various nanocomposite membrane fabrication techniques are also reviewed. This study is important because it gives important information on the roles of nanomaterials and nanostructures in heavy metal removal and wastewater treatment.

“…Charge accumulation at electrode-electrolyte interface is the key element in energy storage mechanism for supercapacitors. Charge storage, electrical conductivity and heteroatom doping are the major factors that influence the capacitor performance [26,27]. The carbon materials like as carbon nanotubes, graphene oxide, carbon nanofibers, and stimulated carbon powder were noticed favorable for supercapacitors owing to high capacitive strength and conductivity.…”

This review is based on the fundamental aspects and applications of polyacrylonitrile (PAN)‐based electrospun composite nanofibers. Various electrospinning techniques have been discussed here. polyacrylonitrile is an acrylic polymer of commercial significance that has superior thermal, mechanical, electrical, and chemical properties. The integration of polyacrylonitrile nanofibers with nanoparticles including carbon nanotubes, graphene nanosheets, graphene oxide, metal oxides, and their combinations has greatly improved the physicochemical properties of the polyacrylonitrile electrospun nanofibers. The enhanced features of polyacrylonitrile nanofibers have resulted from interfacial bonding of nitrile groups with the nanofiller used, chemical compositions, hydrophobicity, porosity, and wettability of these nanofibers. This article fundamentally features a few key possibilities of polyacrylonitrile‐based electrospun composite nanofibers and their applications. A special focus has been made on polyacrylonitrile‐based inorganic nanoparticles, graphene nanosheets, graphene oxide, and carbon nanotubes embedded electrospun nanofibers, for their potential applications in supercapacitors, high power batteries, filtration membranes, electromagnetic interference shielding, and strain sensors. Achieving low cost, high selectivity, excellent recyclability, and high absorption capability are the major challenges for electrospun nanofiber fabrications. These electrospun nanofibers require extensive research in the future to advance the technologies to bring them to the commercial market.
